Our stainless steel toys are compatible with water-based, oil-based, or silicone-based lubes.
Stainless steel has a long shelf life (it doesn’t degrade or fatigue, for example) but you want to be careful not to scratch the surface- so keep it safe from contact with other metals or abrasives. That would include abrasive cleaners.
You may boil your toy for 3-4 minutes to sterilize it, though soap and warm water applied with a soft, damp cloth will clean stainless steel sufficiently. You may also use an adult toy cleaner or 10% bleach solution.
Polish with a soft cloth. Cloths made for auto detailing or eyewear are ideal.
